SynOx Therapeutics funding rounds
| Date | Stage | Investors | Raised | Deal Summary |
|---|---|---|---|---|
| Oct 2024 | Series B | Gilde Healthcare (lead); HealthCap; Bioqube Ventures; Forbion Capital Partners | $92M | SynOx Therapeutics is a late clinical-stage biopharmaceutical company based in Dublin, Ireland, and Oxford, United Kingdom, focused on developing treatments for CSF-1 related and macrophage-driven disorders. Its lead candidate, emactuzumab, is a potentially best-in-class CSF-1 receptor (CSF-1R) inhibiting monoclonal antibody targeting Tenosynovial Giant Cell Tumour (TGCT). On October 30, 2024, the company closed a Series B extension led by Gilde Healthcare, bringing the total round to $92 million, with participation from Forbion, HealthCap, and Bioqube Ventures. Proceeds fund the registrational Phase 3 TANGENT trial, a global, multi-center, randomized, double-blind, placebo-controlled study planning to enroll about 130 patients, with first patients already dosed. The financing strengthens SynOx's investor syndicate, adding Gilde Healthcare's expertise, with General Partner Arthur Franken joining the board. CEO Ray Barlow highlighted the support for advancing emactuzumab to address unmet needs in TGCT patients. Emactuzumab aims to improve quality of life for TGCT patients lacking effective options. The TANGENT trial represents a key milestone toward potential market approval for emactuzumab in TGCT and possibly other indications. |
| Apr 2024 | Series B | Bioqube Ventures (lead); Forbion Capital Partners (lead); HealthCap (lead) | $75M | SynOx Therapeutics is a late-stage clinical biopharmaceutical company developing emactuzumab, a potentially best-in-class CSF-1R inhibiting monoclonal antibody for treating Tenosynovial Giant Cell Tumour (TGCT), a debilitating tumor affecting joint and tendon linings. On April 22, 2024, the company closed a $75 million Series B financing round co-led by Forbion, HealthCap, and new investor Bioqube Ventures, with proceeds earmarked for a registrational Phase 3 trial (TANGENT) and CMC data generation. The funding supports advancement of emactuzumab, which prior Phase 1 data showed to have short treatment cycles, rapid onset, and long response duration. The investor syndicate includes premier life science funds such as Forbion, HealthCap, Bioqube Ventures, and Medicxi, backing a team with proven track records in product development and commercialization. CEO Ray Barlow highlighted the funding as transformational for generating registrational data, positioning emactuzumab as differentiated from other TGCT therapies. Bioqube Ventures' Jon Edwards emphasized the asset's best-in-class potential and the team's capability to reach approval and launch. In October 2024, SynOx extended the Series B with Gilde Healthcare leading additional capital, raising the total to $92 million, while dosing first patients in the Phase 3 TANGENT trial. This extension underscores ongoing support for emactuzumab's late-stage development amid high unmet needs in TGCT treatment. |
| Nov 2020 | Series A | HealthCap (lead); Medicxi (lead); GIMV; Forbion Capital Partners | $44M | SynOx Therapeutics, a clinical-stage biopharmaceutical company based in Dublin, Ireland, with operations in Oxford and Philadelphia, develops emactuzumab, a next-generation monoclonal antibody targeting CSF-1R, primarily for tenosynovial giant cell tumors (TGCT), including diffuse TGCT (dTGCT), also known as pigmented villonodular synovitis. The company is a spin-out from Celleron Therapeutics and secured exclusive worldwide rights for emactuzumab's development, manufacturing, and commercialization from Roche. On November 19, 2020, SynOx closed a €37 million ($44M) Series A financing round co-led by HealthCap and Medicxi, with participation from Forbion and Gimv. The proceeds fund continued clinical development of emactuzumab to generate registrational data for TGCT patients with limited treatment options, aiming for time- and cost-efficient registration as a breakthrough therapy. Emactuzumab has shown profound efficacy in over 60 TGCT patients treated previously, supporting SynOx's focus on macrophage-driven diseases. The financing enables advancement through late-stage trials, including the global, randomized, double-blind, placebo-controlled TANGENT Phase 3 trial in non-surgical TGCT patients, which completed enrollment in August 2025 ahead of schedule, with top-line results expected in Q1 2026. SynOx received Fast Track Designation from the FDA and Orphan Medicinal Product designation from the EMA for emactuzumab in TGCT, highlighting the unmet need. Post-Series A, SynOx strengthened its board with experts like Charles “Chip” R. Romp and Tom J. Heyman for commercialization and strategy. The company is backed by premier life science investors including Forbion, Gilde Healthcare, HealthCap, Bioqube Ventures, and Medicxi. A later Series B round raised $92 million. SynOx explores emactuzumab in other indications and prepares for regulatory and partnering milestones. |
